Hello all,
I recently got the XT926 from Ebay. The phone had CM 10.2 ROM installed when I got it and it could detect my SIM card. Everything worked almost fine. I was able to access the internet through HSDPA and I was able to make calls. However I had issues with not being able to send SMS and MMS. I couldnt save the SMSC number so I decided to install the stable release of CM 10.1. I wiped, and flashed CM10.1 using TWRP that already existed in the phone. Now, after that, the phone will no longer detect any SIM cards no matter what operator or ROM I use. I live in Sweden and I'm using the GSM network. Wifi and all other functions work fine.
I even installed the official VRZ_XT926_9.8.1Q-79-1_CFC.xml but still its not able to bypass the activation screen because it wont detect any sim cards.
Any idea or suggestions on how to fix this?
Thanks in advance

My Girlfriend bought me the new Verizon Samsung S4....not knowing that each phone is "tailored" for the carrier. She used her upgrade for me for Xmas and instead of telling her "i cant use it" and have her feel bad, i would like to Flash a T-Mobile Stock Rom onto the S4.
I currently have my T-Mobile Sim card in the S4, and it actually does work for Voice Calls, but Data wont work. Ive tried configuring several different APNs to it (per T-mobile's website). But i still just cant get Data. I also can not get "wifi calling" because Verizon's Rom does not offer it.
So quick questions:
-Do I need to have Root in order to Flash my Verizon S4, with a T-Mobile Rom. I am assuming Yes.
-Would any T-Mobile, Stock Rom, that works with android 4.2.2 be compatible?
IS IT AS EASY as i am hoping? I am not shy to the Rooting/Unlocking world, so if its possible, i will get it done.
Here is your fix

Any ideas? I m running out
As I said I'm running out of ideas. I tried everything. probably the only solution is a jtag or something to a older rom, then flash cm
So here's my situation.
I have a Verizon Galaxy S3 I535 I have been using on Verizon's network for about 2 years. I am switching to a local carrier that shares towers with Verizon. I am trying to use my I535 on the local carrier. I got a SIM card from the local carrier, put that in my phone and I can make calls and receive text messages but not send them.
In order to attempt to resolve this issue I planned to Wipe the phone and put a custom ROM on to ensure that none of Verizon's software or settings is preventing the texting from working. Problem is I am running KitKat version 4.4.2 that has Verizon's bootloader lock.
I got the phone rooted via Towelroot and CW ROM Manager installed. (rebooted into recovery mode got the "Verizon found unauthorized software yada yada." Got the phone back to a "normal" state with 4.4.2 rooted.)
My questions are:
1. Do you think putting a custom ROM on the phone will resolve my ability to send text messages?
2. Texting works on these same towers using Verizon. Can the backend hardware at Verizon allow the phone to work properly, but not the local carrier? (I have verified Local carrier Galaxy S3 is a different model number)
3. Is it possible to overwrite the bootloader/rom via ODIN
4. Is it possible to brick a phone so bad that you cant even reload the default OS via ODIN

1. Sounds to me like it's not sim unlocked.
2. A custom rom may or may not work in this case, if your on the 4.4.2 OTA your limited to two current roms other than stock using safestrap, disregard the custom rom part
3. The bootloader is locked so once again your limited
4. And yes you could very well hard brick the phone while not doing something correctly

Thanks for the Reply
1. I called Verizon when I was planning to switch. They told me my phone is unlocked to use on any carrier. They also gave me the code '000000' if it isn't unlocked. I never received an error message or a place to put an unlock code when using the new SIM. Do you have a link I can reference to ensure that it is unlocked? I have done several searches and haven't found anything that works. There are several that say to type in secret code *#XXXX# but my phone just attempts to make a call and says "not a valid number". Any help is appreciated.
2. Are you saying that i would be able to put a custom ROM on like Jelly 'Beans' or Clean ROM? If yes, can you post a link for that as well? I have done some extensive searching and most of the results applied to phones that were pre 4.4.x release.

I honestly know nothing about sim unlocking. If it's on 4.3 or 4.4 and it took the OTA your very very limited to what roms you can flash.

My goal would be to install Cyanogenmod on my SM-G920R7, but haven't been able to find too much help. Any of the rooting methods that seem to work on rest of the S6 variants, doesn't seem to work on this one. There is no TWRP available that I know of.
I would really appreciate any possible help. Thanks in advance.
i have the same problem
I think that this version of the s6 (the cspire version) isn't widely available enough and no one has bothered to make a root for it - ive been searching for a long time and still haven't found anything
I'd like to at least be able to root this thing.. On 5.1.1 now.
I have a rooted cellphone of this version (I purchased it rooted), is there any workaround to unlock GSM/LTE bands on this device?
----
Edit... Okay, so I went back to fresh stock with SmartSwitch, then flashed twrp-3.0.0-0-zerofltespr and Unikernel-v9b-BOH1-920P-100815 via odin 3.10.7, and rooted again... any method to enable gsm on this device yet?

How exactly did you root it again? Was it SM-G920R7?

Yes, it was SM-G920R7... first, I flashed twrp-3.0.0-0-zerofltespr , then Unikernel-v9b-BOH1-920P-100815 , both via ODIN (you can google both files), note these files are NOT for r7 version (they're for sprint version *g920p*) but they'll root the phone.
I ended up getting rid of the phone as there's afaik no way to enable gsm on it

That's not true. I finally rooted that model and got TWRP installed, and followed the steps to get the Sprint Galaxy S4 domestic SIM unlocked. I finally got data and texting working last night, but I can't get calls to work for some reason on an AT&T SIM card. It even shows up at AT&T as my provider. AFIK it is now SIM unlocked, the only thing not working is calls like I said. I'm sooooo close to getting this working. I need people with this phone that are doing the same thing i'm doing! I only paid $50 for it! lol
Can u help me get mine unlocked , ive already rooted the phone.

use the cf auto root download this use google to search first one that comes up use that link go to model sm-g920p cspire and sprint uses
the same network . Use odin to install i have same phone and have mine rooted in this way. So far tried using the sprint version custom rom it will work but you can make phone calls but not the data side for phone internet.

Any way to get the G920P roms to work on this variant? I've had luck with them with other c-spire/ntelos/r7 phones in the past. I'd like to flash Renegade to it...

Wonder if anyone has got calls working using GSM sim card? I have the cspire G920R7 rooted with LTE data working using AT&T sim.
Won't receive calls (straight to vmail) and when placing calls dialer says CALL ENDED immediatly after dialing.
hmmm.

I'm working on this too. So far I've got the same situation as you, Data works but no calls/text.
in a few weeks the person who wants me to unlock this phone for them is switching carriers and plans on buying a new phone to use until I can unlock the S6, so I'll have more time to mess with it then.
There's a few things I want to try, but I can't post links here (XDA rules).
One involves Rooting and using a service code to unlock the bands (google "TeamUSCellular GSM unlock S6")
The other also requires rooting and involves using "galaxy tools" to unlock the bands (not sure if this app works with marshmallow, though) (google "theandroidsoul how to sim unlock sprint galaxy S6")
My hopes are not high for getting this phone to work fully. I've also been trying to get custom ROMs to work, but I can't get the cell radio to work at all on custom ROMs. Even with the stock SM-G920R7 Kernel straight from the latest update .tar

Thanks for the suggestion, yeah I have tried galaxy tools (GT) to change the phone mode to LTE/GSM auto and tried different CSC values, and accessed the hidden menus through there. The sim unlock in GT asks for a code which I dont know, but the phone doesn't seem to be locked anyway since it doesn't care when I try different sim cards. Weird thing is the GT app doesn't work very well (most hidden menus not working) on the current rom i'm using but worked better on the stock cspire rom. Note, I tried using MSL 000000 in ##3282# data menu and it works but most the settings in there don't seem to be applicable to GSM networks.
Currently I'VE been messing with the build.prop file, also tried the CDMA to GSM flashable zip which edits the build.prop but nothing has gotten better. One time after editing the build.prop the phone would only turn on with a blank screen and vibrate every few seconds, that was SCARY. Also was planning on flashing other radio/modem but having trouble finding many of those files and pulling them from roms seems difficult to get the correct file to flash on odin.

I'm not sure you'll even be able to flash other models' modem..? I can't say I've ever tried.
Anyway, getting your hands on the firmware is easy. Just use SamFirm (http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647)
To use it, just input the model number (SM-G920R7/R4/P/V/T/A) and the region code, then select "auto".
Region codes and model numbers:
C-Spire: ACG (SM-G920R7)
US-Cellular: USC (SM-G920R4)
Sprint: SPR (SM-G920P)
Verizon: VZW (Locked out from download, app can't download) (SM-G920V)
T-mobile: TMB (SM-G920T)
ATT: ATT (Locked out from download, app can't download) (SM-G920A)
This app downloads firmwares directly from Samsung servers, so the download is really fast and guaranteed to be perfect/stock.
**the SM-G920R7 is closest related to the SM-G920R4 (US Cellular) & SM-G920P (Sprint). The US Cellular one recently supports GSM Bands natively without any rooting/messing with hidden settings, so that's where i'd start. You may not even need the baseband/modem, just flash the rom? I'm not sure. Good luck dude It'd be awesome if you get it working
*** Also, make sure you have a backup of your EFS before messing with the modem. Apparently if you flash an incompatible modem you can erase/corrupt the EFS partition and lose your IMEI. Hell, make a FULL backup with TWRP, and make sure that backup is copied over to your computer before doing any flashing. You can't be too careful with this.
Haven't had any luck flashing stock firmware or modems from other models using Odin, errors with a security message or something, tried G920A and G920R4. Probably for the best I suppose. Flashing custom roms has not been a problem, even if the don't work properly. Wonder if there is a test mode or way to use logcat to see why calls don't proceed like normal. Never worked on going CDMA to GSM before, I always did CDMA to CDMA in the past.
